Currently Teaching

IMGS-616
Fourier Methods for Imaging
3 Credits
This course develops the mathematical methods required to describe continuous and discrete linear systems, with special emphasis on tasks required in the analysis or synthesis of imaging systems. The classification of systems as linear/nonlinear and shift variant/invariant, development and use of the convolution integral, Fourier methods as applied to the analysis of linear systems. The physical meaning and interpretation of transform methods are emphasized.
IMGS-261
Linear and Fourier Methods for Imaging
4 Credits
This course develops the concepts of complex numbers and linear algebra for describing imaging systems in the frequency domain via the discrete and continuous Fourier transforms.
IMGS-322
Physical Optics
3 Credits
Light waves having both amplitude and phase will be described to provide a foundation for understanding key optical phenomena such as interference, diffraction, and propagation. Starting from Maxwell's equations the course advances to the topic of Fourier optics.

    RIT building imaging systems to help libraries and museums uncover lost texts

    Scientists from RIT are developing affordable imaging systems to help libraries and museums preserve and expand access to their historical collections. The project, funded by a grant from the National Endowment for the Humanities, aims to create a low-cost spectral imaging system and software that can be used to recover obscured and illegible text on historical documents.

    Scientists use multispectral imaging to uncover lost text from manuscripts in Croatia

    Croatia has a treasure trove of historically significant manuscripts, but after 800 years of fading ink and worms eating their parchment, much of the text has become impossible to read. Scientists from RIT are using multispectral imaging to make the writing legible once again and preserve the important information the manuscripts hold.
